BAIL-TORPEDU -L Application filed February 17, 1820.

To all whom it may concern:

Be it known that l, HENRY Busrr SrnNonR, a subject of the King of Great Britain, a resident of the city of {)ttawa, Province of Ontario, Dominion of Canada, have inventeo certain new and us iul improvements in Rail-Torpedo Safety and Positive Locks, of which the following is a specification.

This invention relates to improvements in rail torpedo safety and positive locks, and the objects of the invention are to permit of the torpedo lock being secured to the joint of a rail in such a manner that it cannot become displaced, but will be retained in the desired position for firing, to provide means whereby in the event of the rail creeping, so that there is great difficulty in securing the lock to the joint, the torpedo lock may be positively secured to the rail in a firing position, and generally to sim plify the construction of the lock and render the several parts better adapted to perform the functions required of them.

In the drawings:

Figure 1 is a perspective view of a pair of rails in abutting position *ith the improved torpedo lock engaging the joint.

Fig. 2 is a side elevation of the same.

Fig. 3 is a perspective view of the torpedo lock.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings: A represents a pair of rails buttjointed and B the improved torpedo lock secured to the said joint. This lock comprises a plate 10 hav ing a plurality of arms 11 arranged diametrically opposite each other and between the arms 11 shorter arms 12 are provided.

From the lower face of the plate 10 a locking tongue 13 depends, which is formed with a central split 1% so that the two portions of the tongue may be offset relatively to each other, and this tongue is designed to be located between the abutting ends of the rails A.

By forming the tongue 13 in this manner, it will make a frictional locking engagement with the ends of the rail.

When using the torpedo lock, the torpedo is placed on the plate 10 and the arms 11 and 12 are folded over the same to retain the Specification of Letters Patent.

"E-TY AND POFSITIVE LOCK.

Patented Apr. 13, 1920.

torpedo in position and the tongue 13 is then engaged w'th the rail joint and the torpedo is in positionfor firing.

it will be found that the rails sometimes creep, so that it is ditlicult to position the tongue 13 between the joints and under such circumstances the torpedo is placed on the plate 10 and the smaller arms on v are bent over the torpedo, the arms ll being designed in this case to be bent over the ball of the rail to secure the torpedo in position for firing.

in this case the tonguel may require to be bent flat to engage the under side of the plate 10.

From this description it will be seen that have invented a torpedo lock which is positive in its action and which cannot become displaced, much less intentionally reie lock being of an extremely sime and not liable to get out of repie napair.

its many changes could be n'ade in the above construction and many widely different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter containedin the accompanying specification and drawings shall be interpreted illustrative and not in a limiting sense.

That I claim as my invention is:

l. A rail torpedo safety and positive lock comprising means for engaging a torpedo. and depending tongue means from the last said means adapted to be inserted in the joint of a rail.

2. A rail torpedo safety and positive lock comprising plate having arms designed to be bent to embrace a torpedo, and a split depending tongue from the plate, as and for the purpose specified.

8. A rail torpedo safety and positive locl: comprisin a plate having a plurality of arms arranged diametrically opposite each other, a plurality of shorter arms between the said arms, and a split tongue on the plate.

In witness whereof I have hereunto set my hand.

HENRY BUSH SPENCER.
